A man witnesses said grabbed a handgun during a domestic dispute early Wednesday was taken into custody, Melbourne police said.

A woman and her grandson told police that Ryan Peter Drummond, 29, of the 600 block of Burr Street brandished a gun during an argument about money and infidelity, the affidavit states. The grandson said Drummond pointed the gun at his grandmother's head.

When officers arrived to the home shortly after 2 a.m. Wednesday, Drummond was outside, but he ran inside upon seeing the police. He stepped out again holding a cell phone and a bottle of soda, the affidavit states.

Drummond refused to drop the items or follow instructions from the police, according to the affidavit. The officers tackled him and determined he was not armed. They found a gun in a closet in the home, police said.

Drummond was charged with aggravated assault with a firearm and resisting arrest without violence. He was being held without bail at the Brevard County Jail.
